The dickcissel was formally described in 1789 by German naturalist Johann Friedrich Gmelin under the binomial name Emberiza americana. Gmelin based his account on the "black-throated bunting" that the Welsh naturalist Thomas Pennant had described and illustrated in 1785 in his Arctic Zoology.

GBIF citizen-science records
It is estimated from how often the Dickcissel is recorded against all the birds logged in San Antonio (175 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
